I know that if you disconnect the stock recirculating hose on the blow off valve the engine runs rich.
I heard another suby today that definently had an aftermarket blow off valve, because it was definently louder. Is there a way to make the engine run right even know you take the hose off, or do you have to deal with your engine running rich. Personally I couldn't do that. But when my friend took his off. He drove his around like that. Thanks for your help.

 

with some tuning, yes. otherwise you're going to have a very ****ty drive...
if you have a ssqv you may have a better time (it's adjustable to vent or not vent)

 

where and how do i tune for that. thanks
